|
TabFileReader reads tab/return delimited files into 2D arrays.
|
|
|
|
For semi-colon-delimited files use link::Classes/SemiColonFileReader::. For comma-separated files use link::Classes/CSVFileReader::. For space-delimited files, or custom delimiters, use link::Classes/FileReader::.
|
|
|
|
Examples::
|
|
|
|
code::
|
|
(
|
|
// write a test file:
|
|
f = File("TabDelTest.sc", "w");
|
|
f.write(
|
|
"Some tab- delimited items in line 1
|
|
|
|
and then some more in line 3
|
|
"
|
|
);
|
|
f.close;
|
|
)
|
|
|
|
|
|
// open file, read and put strings into array, close file.
|
|
x = TabFileReader.read("TabDelTest.sc").postcs;
|
|
|
|
// can skip empty lines:
|
|
x = TabFileReader.read("TabDelTest.sc", true).postcs;
|
|
|
|
// do file open/close by hand if you prefer:
|
|
f = File("TabDelTest.sc", "r"); f.isOpen;
|
|
t = TabFileReader(f);
|
|
t.read;
|
|
f.close;
|
|
|
|
(
|
|
// write a test file with numbers:
|
|
f = File("TabDelTestNum.sc", "w");
|
|
|
|
(1..10).do { |n| f.write(n.asString ++ Char.tab); };
|
|
f.close;
|
|
)
|
|
|
|
x = TabFileReader.read("TabDelTestNum.sc").postcs;
|
|
x.collect(_.collect(_.interpret)); // convert to numbers.
|
|
|
|
// or you can do it immediately:
|
|
x = TabFileReader.readInterpret("TabDelTestNum.sc").postcs;
|
|
|
|
(
|
|
// write a test file with numbers:
|
|
f = File("TabDelTestNum.sc", "w");
|
|
|
|
(1..100).do { |n|
|
|
f.write(n.asString ++ if (n % 10 != 0, Char.tab, Char.nl)); };
|
|
f.close;
|
|
)
|

x = TabFileReader.readInterpret("TabDelTestNum.sc").postln;
